EL-34 tubes

Ricardo

My Sixpacs came with RUBY EL34's. I want to get a spare set, but don't want to pay too much (12 tubes in total). Was thinking on getting Electro-Harmonix, which I know have good reputation and are amongst the cheapest.

Any other recommendations out there?

Also...are RUBY tubes any good? Where are they in the food chain??

I like my Sovteks.

I run 6CA7EH (fat bottle) Electro Harmonix tubes in my Shanling amps and love them.
